Zonne-energie

De zon is een onuitputtelijke bron van schone energie, en de mens heeft hier door de eeuwen heen op allerlei manieren gebruik van gemaakt. Tegenwoordig staat het opwekken van zonne-energie over de hele wereld in de belangstelling. Yokogawa zet haar expertise nu ook in om met een volledig geïntegreerde besturings- en bewakingsoplossing voor PV- en CSP-energiecentrales op zonne-energie.

Uitdagingen

Customer Challenge

Optimizing power generation efficiency by accurately tracking the sun as it moves across the sky

Customer Challenge

Integrating the various systems and subsystems throughout a plant so as to optimize efficiency and ensure stable operation

Solution

Yokogawa seamlessly integrates the power generation system with subsystems such as the solar collection system and the heat exchange system. This facilitates the monitoring and control of the entire plant, thereby leading to increased efficiency and greater stability.

 

Customer Challenge

Using battery energy management system (BESS) in order to ensure the stable supply of power to the grid even when there is a dip in poer generation

Solution

Yokogawa’s network-based control system with its redundant SCADA helps customer’s stable and profit-maximized operation with following key functions:

• Operation planning and monitoring: Display required information of every BESS integrated in the system in remote control center by multi-screen, and let operators make the setting of schedule for constant power or load following for each BESS.
• Control and operations: Distributing the information to BESS for stable operations such as reference value for demand-power- level, reference-power (active/reactive) from the distribution management center and schedule warning alert.
• Battery monitoring: The charge-discharge rate, charge status and operation status of each battery are displayed.

Concentrated Solar Power Generation Process

A CSP generation system consists of a solar thermal collecting unit, a heat transfer unit, a heat storage unit, and a power generation unit, and is classified into four types according to the solar thermal collection technology: tower, parabolic trough, linear Fresnel, and parabolic dish. All technologies, with the exception of the parabolic dish technology, collect sunlight with reflectors and use the stored heat to produce steam that drives a turbine.

In such systems, the power generation unit is basically the same as that of a thermal power plant. Thus, conventional technologies that have been in practical use can be applied to CSP plants.
